STUD.'

SPECIFICATION forming part of Letters Patent No. 656,598, dated August21', 1900.

Application filed .Tuly 12, 1900.

To all whom, it may concern:I4

Be it known that I, GEORGE R. CLARKE, a

y citizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, have invented a certain new anduseful Improvement in Studs, of Which` the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to that class of studs Whose foot consists of astem at right angles Its object is to secure automatic action and suchlocation of parts as to prevent loss or fracture of the same. ThisobjectI attain by the construction hereinafter described,and illustrated inthe drawings, wherein like letters of reference referto like partsthroughout the views.

Figure 1 is a perspective View of my stud; Fig. 2, a centrallongitudinal section of the head and barrel with parts in normal posi#tion; Fig. 3, a like view with parts distendedf ready for insertion, andFig. 4 is a transverse vertical section on line of Fig. 3.

The construction is as follows: The siudfoot is a barrel ct,longitudinally slotted a convenient distance at b, having one end cclosed and beveled and the opposite end filled by a plug d, whoseprojecting end e is pointed and provided with an annular groove e.

Over this point a gold shell m may be swagedA when the quality of goodsso demands, the

shell tting in the groove e', and thereby be-A ing securely held on theplug-d. The stud-V body consists of a head n and thin posto, the latterhaving its sides grooved at r to facilitate movement within thebarrelslot l). The lower portion of the post has a base sexiending atright angles therefrom, with its rear surface beveled or curved andcarrying upon its forward en d a .rod @fthe whole adapted Serial No.23,297. (No model.)

to slide within the barrel aforesaid. A heli- .cal spring w is fittedWithin the barrel, with one end soldered or otherwise conveniently heldin union with the plug d, While the other spring-terminal is similarlyfixed to the base s.

To operate my device, the stud member is drawn to the rear end ofthebarrel, While the point and body a are inserted into the fabric, asshown in Fig. 3, and the release of tension upon the spring projects therear end of the barrel beneath the fabric, (see Fig. 2,) thus holdingthe stud in place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, i s

As an improved article of manufacture, a stud comprising a slottedbarrel having one of its ends closed and beveled, a head provided with ashank slidably mounted in said barrel and having a base disposed thereinVand extending at right angles to the shank,

said shank being grooved at opposite sides for receiving the edges ofthe slot of the baI'-, rel, a rod carried by said base and projectingtherefrom, a plug arranged in the other end of said barrel and having anoutwardly-projecting point provided with an annular groove, a springarranged in said barrel and interposed between said base and said plug,the

4ends of said spring being connected to the ends of said base and saidplug, and a shell mounted upon the projecting point of said plug andswaged in the groove thereof, whereby said shell is held upon saidpoint.

In testimony whereof I have affixed my signature in presence of twowitnesses. GEORGE R. CLARKE. Witnesses:
